Chrysanthemum plant named `Suerte`

ABSTRACT

A distinct cultivar of Chrysanthemum plant named `Suerte`, characterized by its medium-sized daisy-type inflorescences that are about 9 cm in diameter; attractive dark pink/purple ray florets and bright yellow disc florets; numerous ray florets per inflorescence arranged in multiple rows; numerous disc florets per inflorescence; and excellent postproduction longevity with flowering stems maintaining good substance and color for three to four weeks in an interior environment after one week of cool storage.

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthema grandiflora and referred to by the cultivar name Suerte.

The new cultivar is a product of a planned breeding program conducted by the inventor in Salinas, Calif. The objective of the breeding program is to create new Chrysanthemum cultivars having inflorescences with desirable colors and good form and substance.

The new cultivar originated from a cross made by the inventor in May, 1991, in Salinas, Calif. of two unnamed proprietary seedling selections. The female parent, seedling number 0053, is a daisy spray-type cut Chrysanthemum with dark pink ray florets. The male parent, seedling number 0018, is a daisy spray-type cut Chrysanthemum with bronze ray florets.

The cultivar Suerte was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., in January, 1993. The selection of this plant was based on its desirable inflorescence color, multiple rows of ray florets, and good form and substance.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Alva, Fla., has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

The cultivar Suerte has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Suerte`. These characteristics in combination distinguish `Suerte` as a new and distinct cultivar:

1. Medium-sized daisy-type inflorescences that are about 9 cm in diameter.

2. Attractive dark pink/purple ray florets and bright yellow disc florets.

3. Numerous ray florets per inflorescence arranged in multiple rows.

4. Numerous disc florets per inflorescence.

5. Excellent postproduction longevity with flowering stems maintaining good substance and color for three to four weeks in an interior environment after one week of cool storage.

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The first photograph comprises a side perspective view of a typical flowering stem of, `Suerte` grown as a spray-type cut Chrysanthemum.

The second photograph comprises a side perspective view of typical inflorescences of the cultivar `Suerte`.

The third photograph comprises a top perspective view of adaxial (left) and abaxial (right) surfaces of typical inflorescences of the cultivar `Suerte.`

The fourth photograph comprises a top perspective view of the adaxial (bottom of photograph) and abaxial (top of photograph) surfaces of leaves of the cultivar `Suerte` at three different stages of development showing the differences in size and lobation development.

Floret and foliage colors in the photographs may differ from the actual colors due to light reflectance.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Salinas, Calif., under commercial practice in a polyethylene-covered greenhouse. Rooted cuttings were planted Nov. 7, 1996 and cut flowers were harvested on Jan. 15, 1997. After planting rooted cuttings of the new cultivar, plants received two weeks of long day/short nights following by short day/long nights until flowering. Measurements and numerical values represent averages for six typical flowering stems.

Flowering stem length.--About 89 cm.

Foliage description.--Leaf arrangement: Alternate. Leaf size, fully expanded: Length: About 10.5 cm. Width: About 8 cm. Leaf apex: Cuspidate. Leaf base: Attenuate. Leaf margin: Deeply lobed. Leaf texture: Abaxial and adaxial surfaces slightly pubescent. Veins prominent on abaxial surface. Color: Young foliage adaxial surface: 147A. Young foliage abaxial surface: 147B. Mature foliage adaxial surface: 147A. Mature foliage abaxial surface: 147B. Venation adaxial surface: 147B. Venation abaxial surface: 147B. Petiole: Length: About 2.5 cm. Color: 147B.

Flowering Description

Appearance.--Daisy-type inflorescence form. Inflorescences borne on terminals, arising from leaf axils. Disc and ray florets arranged acropetally on a capitulum.

Flowering response.--Under natural conditions, plants flower in the autumn/winter in the Northern Hemisphere. At other times of the year, inflorescence initiation and development can be induced under short day/long night conditions (at least 13.5 hours of darkness). Plants exposed to 2 weeks of long day/short night conditions after planting followed by photoinductive short day/long night conditions flower about 55 days later.

Postproduction longevity.--In an interior environment, flowering stems will maintain good color and substance for three or four weeks in an interior environment after one week of cool storage.

Quantity of inflorescences.--About 7 inflorescences per flowering stem.

Inflorescence size.--Diameter: About 9 cm. Depth (height): About 1.2 cm. Diameter of disc: About 1.75 cm.

Ray florets.--Shape: Oblong. Size: Length: About 4.25 cm. Width: About 1 cm. Apex: Rounded to dentate. Base: Attenuate. Margin: Entire. Texture: Satiny, smooth, glabrous Aspect: Flat.

Mature: Adaxial surface: 78A/80B with white at base. Abaxial surface: Lighter than 84C/76C with white at base.

Disc florets.--Shape: Tubular. Size: Length: About 7 mm. Width: Apex: About 2.5 mm. Base: About 1 mm. Number of disc florets per inflorescence: About 127. Color: Immature: 154A. Mature: Apex: 9A. Base: Greenish white. Throat: 9A.
